refractive index of glass= 1.5
we know
refractive index =
speed of light on vaccum/speed of light in glass
therefore
speed of glass
=speed of light in vaccum/ refractive index of glass
= 3 x10^8 / 1.5
=30/15 x 10^8
=2 x 10^8
we know
refractive index =
speed of light on vaccum/speed of light in glass
therefore
speed of glass
=speed of light in vaccum/ refractive index of glass
= 3 x10^8 / 1.5
=30/15 x 10^8
=2 x 10^8

hey there,
given that speed of light in vacuum= 1.50
from the relation, n=c/v
speed of light in glass= 3 × 10⁸ m s⁻¹/1.50
by calculating,
required answer = 2 × 10⁸ m s⁻¹.
hope it helps..
